Running the OdorFree ozone generator for several hours will remove mold and mildew smells.
Shock treatment remediation is required to remove mold odor because mold and mildew thrive in damp environments and those areas with poor air circulation. If the area smells musty, there's a good chance that live mold spores are in the air. These spores can reproduce by the millions and damage the building and its contents.
As the OdorFree fills the entire space with ozone, every interior surface including floors, ceilings, closets, furniture and clothing gets treated. While ozone is not able to pass through solid walls, it goes where normal air can go, even down into cracks and crevices.
